UberFire 0.3
by Michael Anstis
Hi,
I've created a uberfire-0.3 branch for droolsjbpm-build-bootstrap; that I
suspect we all extend.
I am starting to take a look at upgrading guvnor, kie-wb-common and
drools-wb to UF 0.3...
With kind regards,
Mike

Drools in Hawaii
by Mark Proctor
I'm going to be in Hawaii for 3 weeks in september, visiting honolulu, kauaui and maui.
Is there a Drools community on any of those islands, I could be tempted to attend a user group and do a Drools 6 talk :)

Re: [rules-dev] [rules-users] Dynamic Rules and Eval
by Wolfgang Laun
It's a bug, possibly a regression from 5.2.0 that has been in 5.3.0,
5.4.0 and is still in 5.5.0.
It should be very simple to add http://codetidy.com/6206/ as a test
case so that this will be fixed.

IMPORTANT: commit messages and BZ tickets
by Edson Tirelli
All,
From now on we were asked to follow 2 additional practices when
committing code to our code repositories:
1. Please always include the BugZilla ticket number on your commit message
when working on a BZ ticket. If you also have the JIRA ticket, please add
that too. E.g.:
git commit -am "BZ-999999 DROOLS-999 : fixing foo far."
2. Please copy&paste the link to your commit into the comments of the BZ
ticket. You can get the link to the commit from github itself or from the
IRC channel, since the bot always pastes the link there when you push your
commit.
This is necessary because the integration of BZ and GitHub is not done
yet. When they integrate them, we will no longer need (2), but (1) is a
requirement.
Thank you,
Edson

kie-tests repository created for integration and other cross-project tests
by Marco Rietveld
Hi all,
I've created a kie-tests repository:
https://github.com/droolsjbpm/kie-tests
The repository is meant for any integration or other cross-project tests
which might not fit in in other modules.
(The reason to create it at this moment was in order to have a place for
some kie-wb integration tests, but the idea of a repository for various
cross-project tests has been one I've talked about with various people
in the last year.)
Thanks,
Marco

Next time do so, it's quite interesting, see below...

Copied your rules into a drl, and 5.5.0 crashes with:

OK, I must not omit an import, but an NPE is uncalled for. So, I added
import java.util.List
and then I get:
### compilation errors ###
Unable to resolve ObjectType 'isRight' : [Rule name='nextTo']
Query's must use positional or bindings, not field constraints:
This error message ought to be rewritten as
"Queries require positional arguments or bindings, not field constraints"
Next, I added some semicolons:
query nextTo(String x, String y, List list)
isRight( x, y, list; )
or
isRight( y, x, list; )
end
query isRight(String l, String r, List list)
l := String() from list.get(0)
r := String() from list.get(1)
tail : List() from list.subList(1, list.size() )
isRight( l, r, tail; )
end
and then I get:
### compilation errors ###
Unable to resolve ObjectType 'isRight' : [Rule name='nextTo']
I had to swap the queries so that the definition of isRight precedes
its use in nextTo. That's a potentially blocking bug, since queries
can be used mutually recursively.
Quite a haul...
